Grade Details — Key Grade Characteristics
The TA grade substrate is a micro-grain tungsten carbide (WC-Co) with a cobalt content optimized for toughness and wear resistance. The advanced multi-layer PVD coating reduces friction coefficient to 0.25–0.35 and increases oxidation resistance up to 850°C.
| Characteristic | TA Grade Value |
| Carbide Grain Size | 0.8 – 1.2 µm (micro-grain) |
| Co Content | 8 – 10 wt% |
| Hardness (HV30) | 1,650 – 1,750 HV |
| Transverse Rupture Strength | 3,800 – 4,200 MPa |
| Coating Type | Multi-layer PVD (TiAlN + TiSiN) |
| Coating Thickness | 2.5 – 3.5 µm |
| Max Operating Temperature | 850 °C |
Grade Comparison Matrix
| Grade | Wear Resistance | Toughness | Best For |
| TA | ★★★★★ | ★★★★☆ | High-speed steel, stainless, general purpose |
| PR | ★★★★☆ | ★★★★★ | Interrupted cuts, unstable setups |
| PV | ★★★★★ | ★★★☆☆ | Hardened steel >50 HRC |
| CA | ★★★☆☆ | ★★★★☆ | Aluminum, non-ferrous (uncoated) |
Chipbreaker Profile
Although solid carbide drills do not feature indexable chipbreaker geometries, the SGS64176 employs an advanced point-thinning and margin-relief design that functions analogously to control chip formation and evacuation:
- Split-Point Geometry (135°–140°): Reduces thrust force by 30–40% and minimizes walk-off on entry.
- Margin Width Taper: Primary margin 0.12–0.15 × D, secondary margin 0.06 × D for stable hole guidance.
- Flute Profile: Parabolic flute grind with polished surface (Ra ≤ 0.2 µm) to prevent chip packing in deep-hole applications up to 5xD.
- Helical Chip Space: 36° helix promotes continuous chip curl and upward evacuation, preventing recutting and edge buildup.
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability |
| Stainless Steel, Tool Steel, Cast Iron | M20–M35 | Excellent |
| Gray & Ductile Cast Iron | K20–K30 | Very Good |
| Aluminum & Alloys | N10–N25 | Good (with polished flutes) |
| Hardened Steel (≤ 50 HRC) | H20–H30 | Good (reduced speed) |
| Titanium & Superalloys | S10–S20 | Moderate (special feeds) |
Application Map by Operation
| Operation Type | Suitability | Notes |
| Through-Hole Drilling | ★★★★★ | Primary application; optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Ensure peck cycle for depths > 3×D |
| Peck Drilling (Deep Hole) | ★★★★☆ | Use 1–2×D peck increments; coolant pressure ≥ 20 bar |
| Stack Drilling | ★★★☆☆ | Clamp plates firmly; watch for interfacial burrs |
| Cross-Hole Drilling | ★★★☆☆ | Reduce feed by 30% at intersection |
| Spot / Center Drilling | ★★★★☆ | Self-centering split point reduces need for separate spot drill |
Recommended Cutting Conditions
Values below are starting parameters for external coolant; increase by 15–25% for through-spindle coolant (TSC) systems.
| Material | Vc (m/min) | fn (mm/rev) | RPM (approx.) |
| Carbon Steel (C45) | 50.0 – 96.0 | 0.111 – 0.231 | 1560 – 2995 |
| Stainless Steel (304) | 38.0 – 72.0 | 0.094 – 0.196 | 1170 – 2246 |
| Cast Iron (GG25) | 55.0 – 106.0 | 0.133 – 0.277 | 1716 – 3295 |
| Aluminum (AlSi10Mg) | 125.0 – 240.0 | 0.2 – 0.416 | 3900 – 7489 |
| Hardened Steel (45 HRC) | 25.0 – 48.0 | 0.067 – 0.139 | 780 – 1497 |
Operating Guidelines
- Coolant: Use water-miscible coolant (8–10% concentration) or neat oil. Minimum flow rate 8 L/min; for deep holes > 3×D, use through-tool coolant at 30–70 bar.
- Run-in: For the first 5 holes, reduce Vc by 20% and fn by 10% to allow the cutting edge to stabilize and the coating to seat.
- Peck Drilling: For 5xD tools, use peck depths of 1.0–1.5×D in steels, 2.0×D in cast iron, and 0.5×D in stainless steels and superalloys.
- Entry Angle: Ensure workpiece surface is perpendicular to spindle axis within 0.5°. For angled entry, use a spot drill or pilot hole ≥ 0.5×D at 90°.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB = 0.15–0.20 mm for steels, 0.20–0.25 mm for cast iron, or when hole tolerance exceeds IT9.
- Storage: Store in original protective tube away from humidity. Avoid contact between cutting edges during transport.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
| ER Collet Chuck | ER25 / ER32 / ER40 | Use AA precision collet (≤ 0.005 mm runout) |
| Hydraulic Chuck | HydroForce, HydroGrip | Excellent damping; ideal for 5xD drilling |
| Shrink Fit | Haimer, Schunk, Rego-Fix | Best rigidity and runout < 0.003 mm |
| Milling Chuck (Power Milling) | NT / BT / HSK-A63 / HSK-A100 | Acceptable for short holes; verify clamping force |
| Taper Interface | BT40 / BT50 / HSK-A63 / HSK-A100 | HSK preferred for high-speed spindles > 10,000 RPM |
